Artificial intelligence discovers secret equation for 'weighing' galaxy clusters

Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had.

AI finds that first stars were clustered together

An international team has used artificial intelligence to analyze the chemical abundances of old stars and found indications that the very first stars in the Universe were born in groups rather than as isolated single stars.

Is 'Oumuamua's odd propulsion a hydrogen fart?

Oumuamua, the first known interstellar object found moving through our solar system, may be propelled by hydrogen gas produced by ice reserves according to international researchers.

Galaxy changes classification as jet changes direction

A team of international astronomers have discovered a galaxy that has changed classification due to unique activity within its core. The galaxy, named PBC J2333.9-2343, was previously classified as a radio galaxy, but the new research has revealed otherwise.

Scientists find a common thread linking subatomic color glass condensate and massive black holes

Physicists show that black holes and dense state of gluons - the 'glue' particles that hold nuclear matter together - share common features.

Life on distant moons

Researchers from the fields of astrophysics, astrochemistry and biochemistry have now determined in a novel, interdisciplinary collaboration the necessary properties that allow moons around free-floating planets to retain liquid water for a sufficiently long time and thus enable life.

The multiverse: our universe is suspiciously unlikely to exist - unless it is one of many

It's easy to envisage other universes, governed by slightly different laws of physics, in which no intelligent life, nor indeed any kind of organised complex systems, could arise. Should we therefore be surprised that a universe exists in which we were able to emerge?

Largest catalog of exploding stars now available

The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data from thePan-STARRS telescope is publicly available via the Young Supernova Experiment (YSE).

Researchers uncover the first bubble in an intergalactic stew

Researchers have found the earliest evidence of parts of the universe that were heated to temperatures more characteristic to the intergalactic gas medium where most atoms reside in the universe today.

Webb Telescope captures rarely seen prelude to supernova

The rare sight of a Wolf-Rayet star - among the most luminous, most massive, and most briefly detectable stars known - was one of the first observations made by the James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments.

Astronomers detect radio recombination lines of carbon/oxygen ions for first time

Scientists detected radio recombination lines of ions heavier than helium for the first time. These lines were assigned to carbon and/or oxygen ions.

Spiral pattern gives clue to how high-mass stars form

New observations have revealed a spiral pattern in a disk of material around a still forming, but already high-mass, baby star. This indicates that there is gravitational instability in the disk, which has important implications for how high-mass stars form.

Astronomers discover metal-rich galaxy in early universe

While analyzing data from the first images of a well-known early galaxy taken by the James Webb Space Telescope, astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy - one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.
